Decorations are made at decorational workbenches, and are used to decorate Cornerstones, Club Worlds & player-made Dungeons and Lairs. Decorations are split into different workbenches and sorted by Biome. Some decorations must be learned from Recipes before they can be made. Most decorations require Glim and a biome-specific crafting material to make.
Some rare decorations are drops, such as the Rare Bird.
